How to question an exercise

Question

I am new to this. How do I complain/ask for clarification about exercises.
In this one

var x = 0;
while(x<6) {
x++;
}
document.write(x);
It says the answer is just 6. Why isn't it 0-6. If it was x+=6; I would understand but it's not and I don't.

Answer 2

var x = 0;
while(x<=6) {
x++;
document.write(x);
}
Use the document.write inside the while loop you have used outside the while loop.
